“…There are many reasons behind this, from the growth in computational power to the economic benefit of using a parametric model to simulate physical phenomena. Today, 3D models serve many fields, including animation of characters [ 1 ] and faces [ 2 , 3 , 4 ], recognition of expressions [ 5 ], face recognition [ 6 ], and inferring body shapes and measurement to be used, for example, in the clothing industry, for virtual try-on [ 7 ], or in the medical field to estimate fat distribution. However, the applications are often limited due to privacy and sensitive information constraints that reduce or block data sharing and aggregation from multiple sources.…”
